Hinge mechanism and keyboard instrument with same

Abstract

The invention discloses a hinge mechanism and a keyboard instrument with the same, and belongs to the technical field of keyboard instrument manufacturing. The hinge mechanism comprises a pair of hinge seats of the same structure; grooves are formed in the hinge seats, installation holes are formed in the positions, close to the grooves, of the hinge seats, and connecting pieces for installing the hinge mechanism are arranged in the installation holes; and the two hinge seats are rotatably connected through shaft pieces, so that the grooves in the two hinge seats communicate with each other to form a wire passing groove. The keyboard instrument comprises at least two keyboards and at least one hinge mechanism, and the two hinge seats of the hinge mechanism are rotatably connected with the two keyboards through the connecting pieces correspondingly, so that the two keyboards rotate with the shaft pieces and the connecting pieces used as centers correspondingly. The hinge mechanism is simple in structure and attractive and elegant in appearance, wiring is convenient, the keyboard instrument can realize three-dimensional rotating due to the fact that the hinge mechanism is installed on the keyboard instrument, the storing and carrying are convenient, and the assembling operation is easy.

Description

technical field [0001] The invention relates to the technical field of keyboard musical instrument manufacturing, in particular to a hinge mechanism and a keyboard musical instrument with the hinge mechanism. Background technique [0002] At present, existing electronic keyboard instruments such as electric pianos and electronic keyboards are integral structures. They have the characteristics of large volume, heavy weight, and inconvenient portability. They are not mainstream hand-rolled electronic keyboard instruments. Although they are easy to carry, the feel and sound effects are not realistic. The mainstream electronic piano among the keyboard instruments is usually a horizontal keyboard, which is not only clumsy and difficult to store and carry, but also takes up a lot of space, and must be placed on a shelf or table to play, which cannot meet the needs of various use angles and various places. .

Problems solved by technology

[0002] At present, the existing electronic keyboard instruments such as electric pianos and electronic keyboards are of integral structure. They have the characteristics of large volume, heavy weight, and inconvenient to carry. They are not mainstream hand-rolled electronic keyboard instruments. Although they are easy to carry, the feel and sound effects are not realistic.

The mainstream electronic piano among the keyboard instruments is usually a horizontal keyboard, which is not only clumsy and difficult to store and carry, but also takes up a lot of space, and must be placed on a shelf or table to play, which cannot meet the needs of various use angles and various places.

In order to solve the above problems, there is currently a keyboard instrument with two electronic pianos spliced ​​together on the market, which is to connect the two pianos through a connecting mechanism to form a single piano, but the above-mentioned keyboard instrument cannot really realize the three-dimensional rotation of the two pianos.

There are also some keyboard instruments that can be connected by two-dimensional rotation, but the wiring is complicated and the operation and assembly are difficult. If the connecting mechanism is designed to be small, the connecting mechanism cannot be equipped with a plug. , is not conducive to improving production efficiency and saving costs
